Diet Coke is currently facing a shortage in several major cities across India, including Delhi, Mumbai, Bengaluru, and Ahmedabad. This scarcity is attributed to a 14-20% rise in aluminium prices, which have reached four-year highs of approximately $3,672 (₹3.45 lakh) per tonne, exacerbated by geopolitical tensions and logistical delays. Despite the beverage's popularity—sales doubled last year, with low-sugar drinks making up nearly 30% of Coca-Cola India's volume by 2025—production is running nearly 20% below demand. Local vendors are feeling the pinch, with some suggesting alternatives to customers due to stock shortages. Cafes and restaurants are monitoring their supplies closely, with some even embracing the situation by hosting themed events. The Coca-Cola company has acknowledged the challenges on its global FAQ page, noting that increased home consumption and ingredient shortages have impacted its supply chain in various regions.
